CALLEJA MULTIPLE CUTTER PLANE 2 Sheets-Sheet 2- Filed NOV. 25, 1931 Patented May 30, 1933 UNITED STATES JOHN OALLEJA, OF CORONA, NEW YORK MULTIPLE CUTTER PLANE Application filed November 25, 1931.

The invention relates in general to a multiple cutter plane of the type designed to cut ridges, grooves, channels and the like in wood structures and the invention is particularly designed for use in forming grooves, channels, and like recesses in window and door framing for the purpose of receiving conventional forms of weather stripping devices.

\Vith the different forms of weather stripping for windows, doors and like openings, now in the market, it is required that they be inset in the edges of the window and door frames and the installation requires that these grooves, channels and other formed structures be definitely and accurately located in position, each special make of weather stripping requiring its own particular dimension, form and location of containing groove or recess. It is a usual practice at present for the mechanic who mounts the different weather strips in position to carry with him an assortment of planing tools, one for each particular kind and size of groove or recess to be cut in the window or door frame. It is obviously inconvenient to carry the presently required large number of different size and types of planes and in actual practice the mechanic who goes outside of his shop to install a weather stripping on remote premises usually carries with him only the most necessary of these tools, depending upon his personal skill to insure the proper locating of the different cuts relative to each other. It is a practical difficulty present even when such mechanic has available all the necessary types of planes to insure the requisite accuracy in locating the several types of cuts relative to each other and relative to some common plane of reference, such as the side of the door or window frame.

The primary object of the present invention is to provide a simplified and inexpensive form of plane complete as a unitary article particularly designed for use in forming the weather strip containing grooves and cuts now required to mount standard forms of weather stripping devices. Incidental to a this general object, the invention has for Serial No. 577,220.

other objects the fabrication in a single tool of all the necessary cutters to form the grooves most commonly required in mounting weather stripping in place and with the cutters so arranged relative to each other that two or three grooves may be formed singly, or in selected combinations to form the requisite configuration of cut and with the cutters so organized and arranged that they may be set in fixed relative relation and thereafter utilized selectively to form the required configuration of out without necessity of further adjusting the cutters.

Still another object of the invention is to provide in connection with the cutter organization above described, a depth gauge to permit variations in the depth of one of the grooves disclosed in the device illustrated, in order to accommodate the tool to two standard forms of weather strip containing grooving.

Various other objects and advantages of the invention will he in part obvious from an inspection of the accompanying drawings and in part will be more fully set forth in the following particular description of one form of mechanism embodying the invention, and the invention also consists in certain new and novel features of construction and combination of parts hereinafter set forth and claimed.

In the drawings:

Fig. 1 is a view in elevation of the left side of a multiple cutter plane illustrating a preferred embodiment of the invention and with parts of the adjustable side guide broken away to expose two of the cutters;

Fig. 2 is a similar view of thereverse or right hand side of the. plane shown in Fi Fig. 3 is a plan view of the underside ofthe plane shown inthe preceding figures with the adjustable guide shown in two positions, one shown in full line, close to the stock of the plane and the other in distended position as shown in dash lines;

Figs. 4 and 5 are transverse sectional views taken respectively on the lines 44 and 5-5 of Fig. 1, looking in the direction indicated by the arrows and in each case showing the plane on one of its operative positions grooving a piece of work.

Figs. 6 to 8 inclusive are detailed transverse sectional views showing different forms of grooves cut by the plane herein disclosed and showing the relation of the plane to the parts of the work operated upon; and

Figs. 9 and 10 are transverse sectional views of two J-strips formed by using the plane illustrated in two different ways on each piece of work.

The plane taken as a whole is of a somewhat conventional long narrow type including a stock 10 having at its rear end a handle 11 and at its forward end a knob 12. The handle and knob portions are connected by an upstanding medial wall 13 and to the left side of this wall the stock is provided with a pair of inclined seats 14 and 15 for receiving respectively bit sets 16 and 17. The seat portion for the bit set 16 is wider than the seat portion for bit set 17 as shown at 38 in Fig. 3. The bit sets 16 and 17 contain respectively cutters 18 and 19, the lower cutting edges of which extend through the bottom face 20 of the stock 10. It is noted from the showing in Fig. 1 that the cutting edge 21 of the forward cutter 18 is positioned in a plane above the horizontal plane containing the cutting edge 22 of the cutter 19. The stock 10 is provided on its underside with a plate or rather two plates 23 and '24 constituting a replaceable bottom bearing face for the plane through which the cutting edge 22 extends as shown in Figs. 1 and 3. For the purpose of varying the distance or depth of out between the plane of the bearing faces 23 and 24 and the cutting edge 22, it is herein suggested that one or more shims 25 be positioned between the lower bearing plates 23 and 24 and the bottom face 20 of the stock. Readily replaceable flush screws 26 are used to secure the bearing face members and the shims in position on the underside ofthe stock. The bearing face and its associated cutter 19 is relatively wide, in the instant case being one inch.

The portion of the stock in advance of the slot 27 between the adjacent edges of the plates 2324 and through which slot the cutting edge 22 projects and which supports blade set 16 is wider than the part which has the bearing plate 23 mounted thereon. While the upper part of cutter 18 is almost as wide as the cutter 19, and its cutting edge wider, most of its cutting edge is covered by plate 23, as noted in Fig. 3. This leaves a relatively small portion 21 exposed, in the illustrated case a distance of five-eighths of an inch, positioned above the plane of the bottom bearing face a distance equal to the thickness of the bottom plate 23 plus the distance provided by the aggregate thickness of the shims used.

Positioned on the left side of the plane,

that is the side which is provided with the exposed portion of the cutter 21, there is a longitudinally extending adjustable guide strip 28 opposite ends of which are provided with bosses 29 and 30 through which extend carrying screws 31 and 32, for limiting the outward setting of the guide strip and which guide strip is locked in its adjusted position by clamping thumb screws 33 and 34 passed through the guide strip and designed to be screwed into binding engagement with the long screws 31,32. The guide strip is provided on its inner side with three blocks numbered from front to rear of the plane 35, 36 and 37 and which blocks form in effect continuations of the bearing surface provided by the wide portion 38 of the stock 10. The block is disposed to fit in the space in advance of the portion 38 and the blocks 36 and 37 in rear of this portion and on opposite sides of a depth gauge 39 hereinafter described.

Secured to the opposite or right hand side of wall 13 as shown in Fig. 2 is an attachment 4O fixedly secured in position by means of screws 41. This includes a two part strip. invertedly L-shaped in cross section as shown in Fig. 4 and provided with an up wardly extending inclined seat 42 for receiving a. relatively narrow channel bit set 43. This set includes a cutter 44, the cutting edge 45 of which projects through an open ing 46 formed in the narrow flange 47. It is noted from the showing in Fig. 4 that the cutting edge 45 extends in a horizontal-plane above the plane containing the edge 22 and below the plane containing the edge 21 of the other two cutters. The lower edge of the flange 47 is relatively narrow, in the instant case being one-eighth of an inch,

and is spaced from the adjacent side of the stock to form a fixed width channel 46. The side guide 28 on the opposite side forms a variable width channel 471 into the inner portion of which extends the cutter 21.

It is required in actual practice that the fixed width channel be of two depths and in order to provide for this variation in depth required, a transversely movable slide 39 has a reduced inner plate like end 48 disposed to be projected into the bottom part of the channel 46 as shown in Fig. 5 or to be withdrawn therefrom as by shifting this slide to the right from the position shown in Fig'. 5, this being conveniently attained by means of a laterally projecting finger piece 49 for moving the slide back and forth in the guideway 50 provided therefor in the stock and in the adjustable side guide 28.

In operation it will be understood that in general the plane is used conventionally after it has been adjusted to perform the particular cutting operation for which .it is about to be used. In the several figures,

there has been disclosed suggestions as to the character of the out which can be obtained.

For instance, referring to the showing of the work a, in Fig. 4, it is appreciated that groove b may be formed inset from guide edge 0, a distance equal to the width of the fixed width gauge. If the edge a should be inset, along the dotted lines it is appreciated that the grooves I) would be open on one side to form a shouldered construction. Referring to the showing of the work a, in Fig. 5, there is formed a groove (Z of less depth than the groove b due to the intrusion into the fixed width channel of the portion 48 of depth gauge 39 and there is also formed a wide channel 6 in spaced relation to the guide edge a. In the showing of the work in Fig. 6, the flange 47 is used as a guide for spacing the wide grooves e from a guide edge 7* or the edge 0 may be regarded as the guide edge engaging the adjustable guide strip 28. In this case, there is formed a preset form of face to the work in which an intermediate face 9 is formed by the cutter edge 21 with a ledge h projecting into the space between the stock and the outwardly adjusted guide strip 28. It is obvious that the width of the work may terminate at any other point than as indicated at f, such for instance, as along the dotted line f, in which case there will be formed a wide shouldered portion at p.

Referring to the work a, as shown in Fig. '7, the edge 0 may be disposed against the adjustable strip 28 and in this case grooves 72 and e are formed respectively by cutters 4A- and 19 and the top surface 9 by the cutter 21 which, of course, brings the top of the work a, on the right hand side at a lower level than the top of the work on the left hand side of this showing.

Not only can the plane be used in a direction parallel to the top surface of the work on which it is engaged but it may be inclined to this surface and in Figs. 8 to inclusive are some suggestions as to how the plane may be so utilized. For instance, if the plane is worked along one of the edges at an angle to both of the adjacent sides, as suggested in Fig. 8, a V-groove i will be formed by the cutter 44 in one side of the work and a V-shaped trough j formed on another side. By decreasing the angle between the top surface In and the line of the cutter 2-2, the V-shaped trough 7' can be made L-shaped and by shifting the plane to the left the cutter 44 can be removed from its cutting engagement with the work.

Similarly the work shown in Fig. 9 may be formed into the J-shaped structure illustrated by utilizing the cutter 44 to form the upstanding portion Z moving up into the fixed width groove 46 during this operation and then by inclining the plane at an angle the cutter 22 may be utilized to form the inclined surface m. Another similar stepped form of work may be attained as illustrated in Fig. 10 by off setting the adjustable guide 28 a distance equal to tl e width of the desired ledge a so that part a may project upwardly to the outside of the cutter 21, the cutter 21 forming the surface 0; then by p0 sitioning the plane at an angle as previously suggested, the wide cutter 22 is used to cut the inclined surface p.

It is obvious from these suggested illustrations that various combinations of cuts may be obtained by suitable combinations of the several cutting surfaces working either singly or in combinations. The form of work illl'zstrated for instance, in Fig. 7 is a desired form of edge to a window or door frame, particularly designed to accommodate a known form of weather stripping construction. in this instance, it is simply necessary to set the adjustable guide 28 so as to accommodate the tool to fit against the edge 0 wherever it may be relative to the desired cut at g and then by working the plane back and forth conventionally, the lowered surface g, the wide channel 0 and the narrow groove 3) are formed simultaneously, quickly and without attention on the part of the operator to assure the proper relative location of the several cuts to form the desired configuration of surface.
